Thread: If its not the alternator, what is it?

i have an 02 gp 3.1.. my cars been acting wierd, the dashboard lights / radio will shut off and come back on like i lost a quick connection.. the battery light comes on and goes off as it pleases, we checked the battery while it was running and it said it was getting no charge so i replaced the alternator and it still says no charge.. what else could it be? and where should i check for shorts?

Bad ground
Bad battery

I'm with slow on the bad ground.... check to make sure the ground wire is connecting to the neg post on the battery... i've have a problem with the rubber boot on the neg sidepost....when u tighten the sidepost bolt it wont tighten the ground flange to the battery like it should... i just used a washer to fill the gap and conduct properly

Thanks guys it turned out to be the battery was shot.. i didn't think a bad battery would mess everything up like it did..
